Abstract: The invention relates to a method for manufacturing a concentrate enriched in iron mineral content from an ore, which contains an iron mineral and silicate, by reverse flotation, which method comprises the step of (c) adding a compound of formula I wherein R 1 is C 9 -C 22 alkyl or alkenyl, which is linear or branched, R 2 is H, C 1 -C 4 alkyl, which is linear or branched, R 3 is -X-NH 2 , H or C 1 -C 4 alkyl, which is linear or branched, and X is C 2 -C 4 alkylene, which is linear or branched, or a salt of a protonated compound of formula I and an anion, to a prepared aqueous pulp of the ore and optionally one or more flotation auxiliaries to obtain an aqueous mixture. Furthermore, a method for manufacturing a specific group of compounds of formula I, i.e. compounds of formula l-X wherein R 1 is C 9 -C 15 alkyl, which is linear or branched, R 2 is H, R 3 is -X-NH 2 and X is C 2 -C 4 alkylene, which is linear or branched, is disclosed.
